Arcadem Pro 2.7 introduces a “user challenge system” which allows registered users to challenge each other to a game. Whoever gets the highest score wins, and is awarded “Arcadem Points“. Users can challenge other users by visiting their profiles.

Note that challenges are only available on highscore games.  In addition, Arcadem Pro only knows about highscores games that have at least 1 highscore submitted.  For example, lets say you’ve just installed 1000 highscore games, however no onse has played them.  That would mean that none of these games would register as highscore games yet, and thus no one can use them in challenges.  However, once people have played the game once, and any highscore (even 0) is submitted, then the game will be available from the drop down box for the challenge.
